I'm a Celebrity...Get Me Out of Here!. Broadcast on ITV1[Supplied by WENN]

Last month (Nov17), the popular YouTube personality, 23, controversially left the ITV1 show after racist, homophobic and otherwise offensive tweets he had sent as a teenager were published in U.K. newspapers. Speaking on British daytime TV show Lorraine, Jack said he knew he had behaved stupidly in the past, and tried to take precautions - but found it impossible to cover his tracks. "I knew I'd definitely done some really stupid things in the past on social media, and I deleted (the tweets) around a year before I went into the jungle, but there's always that chance (they could resurface)..." As a word of warning to other young fans he added, Be so careful with everything you put online, you leave such a massive footprint. You don't know who's out there looking, who's taking pictures of it all. Just really step back for a moment and think about everything you're going to say and the people that you could hurt or upset." In his tweets, the YouTube star used a gay slur, an offensive racist term, and joked about "raping" women. He also pestered a 14-year-old girl to send him pictures of herself in her underwear but said he had no idea of her age and was 16 years old himself at the time. Quizzed by host Lorraine Kelly as to what he was thinking when sending the tweets, he explained, "I don't really know...I was just being young, stupid, inconsiderate. I wasn't kind of thinking about the weight of those words, what they carried, who I could hurt. I was just retaliating in quite a horrible way. I wish I'd just taken a step back and thought about it." As a result, he left the reality TV show, for which famous figures try to endure weeks in a camp in the Australian jungle, in disgrace. Admitting the plane journey back to the U.K. was incredibly difficult, he added, "I was stuck on a plane for 22 hours with everything in the back of my mind of what could possibly be going on back at home. I just wanted to film the video to apologise about everything." After the scandal broke, Jack, the younger brother of the singer Conor Maynard, lost out on marketing deals with brands including The Body Shop, Walkers and Snickers, but is now attempting to make amends and rebuild his career.
